Hidryte Ebb · The week-before mineral

Flat in the morning. Can't button them by night. That was never fat.

90-Day Money-Back Guarantee
Five Ingredients — All Named
No Laxatives · No Caffeine

Some women get it after every meal. For most, it peaks the same week every month — the week before your period, when your jeans stop fitting on a schedule. Ebb is 275 mg of magnesium glycinate built for exactly that week: the mineral your body runs lowest on, right when it's holding the most water.*

Built for the week-before. The 5 - 7 days before your period, when the bloat arrives on schedule.

90-Day Guarantee — three full cycles

Use Ebb through three week-befores. If nothing changes, email us one line — we refund everything, and you keep the bottles. Nothing ships back.


What it is +

Ebb is 275 mg of elemental magnesium from 2,500 mg of magnesium glycinate — the gentle, absorbed form — built for the week before your period, when your magnesium runs low and everything slows and swells.* Five ingredients. No laxatives, no caffeine.

What's in it — the whole label +

Magnesium (275 mg elemental, from 2,500 mg magnesium glycinate), hypromellose (the vegetable capsule), rice flour (the filler), magnesium stearate and silicon dioxide (the anti-caking agents). Nothing proprietary.

How to use it +

Three capsules with dinner or before bed, every night. Count back seven days from your expected period — that's the week that matters most, so start your first bottle there. One bottle is one full cycle.

How long it takes +

Not overnight — magnesium works with your cycle, not the clock. In the published research, the difference showed in the second cycle, not the first.* That's why the pack is three cycles — and why the guarantee covers all three.

Shipping +

Ships from our US fulfillment center. Free US shipping on the 3-Cycle pack and subscriptions; $4.95 on one-time single bottles. Tracking emailed the day it ships. (We can't ship to Alaska or Hawaii yet — sorry.)

Nothing hurt more than feeling like I lost my own body for a week every month. Ebb gave me that week back.

First — is this you?

If you can check two of these, it was never fat.

You're flat when you wake up.

It inflates through the day — worst after meals, or the week before your period.

Some days it just… doesn't happen.

No diet has ever touched it.

Fat doesn't triple between breakfast and dinner, and it doesn't obey your cycle. What does that is bloating — and if you're like most women dealing with it, you've already spent money trying to fix it.
You're not imagining it

The same week, in thousands of women's own words.

These are real, public posts from women describing this week — lightly edited for length, anonymized, and not reviews of Ebb.

You've already tried the fixes. Here's why each one half-worked.

Midol

Its bloat ingredient is pamabrom — a diuretic — plus an antihistamine. It pulls some of the water. It does nothing about the rest.

Treats: water only

Gas-X

Simethicone breaks up gas bubbles. If your bloat were only gas, it would have worked already.

Treats: gas only

Enzyme pills

Built to digest a heavy meal. If your bloat only followed pizza, they'd have worked by now.

Treats: food bloat

The PMS gummies

One formula chasing twelve symptoms — mood, skin, cramps — with your bloat as a footnote. Nobody ever made your bloat the point.

Treats: your bloat last

Water pills & teas

More diuretics. Same half of the problem, harsher delivery, and the puffiness comes straight back.

Treats: water only

None of them finished the job. Not because you're broken — because they were each built for a different bloat.

The part nobody explained

Your bloat is two problems wearing one name. Everything you tried treats one of them — at most.

In the days before your period, two things happen at the same time. Your hormones tell your body to hold water — that's the overnight "5 pounds," the tight rings, the puffy face. And progesterone slows your digestion down — that's the trapped, stretched, "months-pregnant" firmness that no water pill has ever touched.

Problem 1 — the water your body holds

Hormonal shifts before your period signal your body to hold on to water and sodium.

What Midol & teas half-treat

Problem 2 — the slowdown

Progesterone slows the gut. Things sit, stretch and press outward — the distension you can't suck in.

What nothing you tried treats
We call it the half-treated bloat. Every product on the shelf picks one half, half-works, and lets you conclude your body is the problem. It isn't. And here's the detail that makes it fixable:
Your magnesium drops at exactly the wrong moment. Through the last week of your cycle, magnesium dips — right as your body is holding the most water. Magnesium is the one mineral working both sides of this: it helps your body let go of the water it's holding, and it keeps digestion moving.*
Through the last week of your cycle, magnesium dips as the water your body holds rises — the week before your period.
In published research, women who took magnesium in the run-up to their period had significantly less premenstrual fluid retention — the weight gain, the swelling, the bloating — than women taking a placebo.* You weren't failing. Nothing you tried ever put the mineral back.
Why Ebb, specifically

Not all magnesium is built for this week.

Most magnesium on the shelf is either poorly absorbed (the cheap forms your body mostly passes through) or deliberately laxative — the citrate powders that "debloat" you by sending you running to the bathroom. Neither is something you can take calmly, daily, the week you already feel at war with your body. And if a drugstore magnesium ever "sort of helped" before it sent you running — you've met the mineral. You just hadn't met the form.

Ebb is 275 mg of elemental magnesium from 2,500 mg of magnesium glycinate — the form bound to glycine, known for being the best-absorbed and least disruptive way to take it. No laxative effect. No caffeine. No dash to the bathroom. Gentle enough for every single day of the month — strong enough for the one week that matters.*

The week-before ritual

Begin seven days before your period.

1

Mark the week

Count back seven days from your expected period. That's your start date. (On the 3-Cycle plan, our Week-Before Reminders do this for you — an email the day it's time.)

2

Three capsules, nightly

With dinner or before bed, every night — through the week and the rest of your cycle. That's the entire protocol. One bottle is one full cycle, and the mineral is in place before the water is.

3

Let the week arrive

Same calendar, different week. Less of the overnight swell, less of the can't-button standoff — building cycle over cycle.*

The label, in public

Five ingredients. None of the trap.

Every one named, with its job.

EVERY LINE FROM THE LABEL — serving size 3 capsules · 30 servings per container
Magnesium
the mineral — 275 mg elemental, from 2,500 mg magnesium glycinate, the absorbed form
275 mg · 65% DV
Hypromellose
the vegetable capsule
Rice flour
the filler. Nothing more.
Magnesium stearate
keeps capsules from sticking to the machines
Silicon dioxide
keeps the powder dry
On your bottle this prints the regulation way: magnesium in the Supplement Facts panel, the other four on the "Other ingredients" line. Same five. Nothing else.

No enzyme blend pretending your dinner is the problem. No diuretic pretending it's only water. No proprietary blend hiding the doses. Read it — that's the whole pitch.

The honest timeline

What to expect, cycle by cycle

Cycle one

The edge comes off

The mineral gets in place before the water does. If anything shifts this cycle, it's the size of the morning-to-night swing — smaller, not gone. Don't call a verdict yet; the research didn't either.*
Cycle two

Where the research points

In the published study, the significant difference vs placebo showed in the second cycle. This is the week you compare jeans, not feelings.*
Cycle three

The believer cycle

The week-before arrives and it's just… a week. This is the cycle our guarantee is built around.
Anyone promising you a flat stomach by tonight is selling you the diuretic again.
Choose your cycles

One bottle tests your patience. Three tests the product.

The research showed the full effect in the second cycle. So the third bottle — the one where you believe us — is on us.
The guarantee

90 days. Three full cycles. Zero forms.

Use Ebb through three week-befores. If the third one looks and feels like the ones you're living now, email us one line and we refund everything. Keep the bottles — nothing ships back. We're guaranteeing the cycle the research points at, not a lucky first week. (Started with one bottle? Same 90 days, same one-line email.)

Who this is for — and who it isn't

Ebb is for you if…
  • Your bloat runs on a schedule — after meals, and worst the week before your period
  • You own "that week" jeans, or a dress that hides it
  • You've done the Midol / Gas-X / enzyme tour and quietly concluded you were the problem
  • You want something gentle enough to take every day, not another harsh flush
It's not for you if…
  • You want a flat stomach by tonight — that's a diuretic, and you already know how that ends
  • Your bloating is constant, painful, or new — that's a conversation for your doctor, not a supplement
  • You're pregnant, nursing, or on medication — check with your physician first

Every question you should ask

Isn't this just magnesium? I can buy that for $13 on Amazon. +

The molecule, yes — and we'll never pretend otherwise; the label is public. What the $13 bottle doesn't come with: the right form at the right dose (many cheap bottles are the laxative form, or a form that's rough on your stomach), the week-before protocol timed to your cycle, the Week-Before Reminders on the 3-Cycle pack that make you actually take it during the week that matters, and a 90-day guarantee from a brand built around this one problem. You're not buying a mineral. You're buying the system that makes the mineral land on the right week — with your money back if it doesn't.

I've tried Midol and the enzyme pills. Why would this be different? +

Because they treat different halves of a two-part problem. Midol's bloat ingredient is a diuretic — water only. Enzymes digest food — food bloat only. Magnesium is the one mineral involved on both sides: fluid balance and keeping digestion moving. That gap has a name — the half-treated bloat — and it's the gap everything you tried left open.*

Will this help me lose weight? +

No — and that's the point. Fat and bloat are different problems: fat doesn't arrive overnight and leave by week two. Ebb supports normal fluid balance and digestion around your cycle* — it does nothing to body fat. Any product that promises to handle both is lying about one of them.

How fast will I notice something? +

Honestly: this works on cycle time, not clock time. Ebb supports normal fluid balance and digestion through the week-before* — the kind of change you compare across cycles, not hours — and in the published research, the difference vs placebo showed in the second cycle. If a product in this category promises tonight, it's a laxative or a diuretic wearing a wellness label. Our guarantee covers three full cycles precisely so you never have to take our word for it.

Why glycinate and not citrate? +

Citrate is the laxative form — it "works" by pulling water into your bowel, which is the last thing you need that week. Glycinate is magnesium bound to glycine: gentle on the stomach, easy to absorb, no laxative effect — the only form that makes sense to take nightly through your whole cycle.

My cycle is irregular — will this still work? +

That's what the protocol is built for — it keys off your expected period, not a perfect 28-day clock. Start when your body's signals (or your tracking app) say you're about a week out; and if the week surprises you, start the night you notice — Ebb is gentle enough for any day of the month. On the 3-Cycle plan, the Week-Before Reminders adjust with whatever dates you give us.

Is this safe? Can I take it with my other supplements? +

Magnesium glycinate is one of the most-taken, best-tolerated supplements there is, and Ebb is made in an FDA-registered US facility. With other supplements, one honest check: read your other labels so you're not doubling up on magnesium a multivitamin already gives you. And if you're pregnant, nursing, under 18, on medication, or have a medical condition — ask your physician first. That's not legal boilerplate; it's the correct order of operations.

How does the subscription work? Is it a trap? +

No trap, by design: it's opt-in only (never pre-ticked), the next ship date is always visible in your account, and skip or cancel is one click — no chat window, no phone call, no "retention specialist." We'd rather earn the reorder with your third cycle than trap it with a checkbox.

How does the guarantee actually work? +

Buy Ebb, use it through up to 90 days. If your week-before hasn't changed, email support@hidryte.com — one line, no questionnaire — and we refund the full price. You keep the bottles. We can offer that because the window matches the mechanism: three cycles is a real test, and we're betting Ebb passes it.

Where does it ship from, and how long does it take? +

From our US fulfillment center. Orders typically ship within 2 business days and arrive in about 3–7 business days. (We can't currently ship to Alaska or Hawaii — sorry.) Free shipping on the 3-Cycle plan; $4.95 on single bottles.

Will the bottle scream "period product" on my counter? +

No. Anyone reading the front of the bottle learns exactly one thing: you take a mineral. The week-before is your business — the label keeps it that way.

Your next week-before is already on the calendar.

You know the date. This time you can be ready for it — or you can be back in the "that week" jeans, waiting it out again. Three cycles, 90 days, money back. Read the label first. Then decide.

Start before your next week-before
